How to redeem codes in Build A Gun
Step 1: Start the Build A Gun experience on Roblox and load into the game.
Step 2: Look at the left side of the screen and click the Codes button.
Step 3: In the window that appears, click the text box labeled “Enter codes here”.
Step 4: Type or paste a working code exactly as shown, then press the Enter key on your keyboard.
Step 5: If the code is valid, the reward is granted instantly to your account. If nothing happens, double‑check spelling and spacing, then try again.
How to confirm your Build A Gun code worked
After redeeming a code, you can quickly verify it by checking the relevant area:
- Cash codes – Your cash balance in the main HUD increases immediately.
- Weapon codes – The Diamond Shotgun or Diamond Submachine Gun appears in your guns list and can be placed in your base.
- Spawner codes – The Rusty Spawner is added to your available spawners for enemy waves.
- Effect codes – Potion Effects become selectable where the game manages cosmetic or gameplay effects.
Why a Build A Gun code might not work
If a code does not redeem, the most common reasons are:
- Typing or spacing mistakes – Codes are case sensitive and some contain spaces or punctuation. Make sure everything matches exactly.
- Extra spaces – Leading or trailing spaces in the text box can cause the code to fail.
- Server version – Rarely, an older server can cause issues. Leaving the experience and joining a new server can help.
If a code still fails after checking these points, it is likely no longer valid.
What Build A Gun codes give you
Each current code focuses on accelerating early progression or giving you unique items:
- Scruffy / 1M Visits – Straight cash injections for faster upgrades and more guns.
- 244466666 / Late Christmas – High‑end Diamond weapons so your defenses hit harder without long grinding.
- : code: code: code: – A Rusty Spawner to increase enemy waves and income potential.
- 100k Visits – Potion Effects that add special effects on top of your usual setup.
Using these rewards early lets you set up a stronger base, spawn more enemies, and clear stages faster than relying on starting gear alone.
